Metodología topográfica para la instalación de tuberías de poliéster reforzada con fibra de vidrio – GRP en el canal Cauquita de la ciudad de Cali

Abstract

The methodology used in the installation of GRP-FIBERGLASS REINFORCED POLYESTER is presented, in the CAUQUITA CHANNEL, located in the Alfonso Bonilla Aragón neighborhood of the city of Cali - Vale del Cauca, with the purpose of establishing technical parameters in all its stages from georeferencing, topographic survey, trench opening with slope, assembly, insertion methods, coupling and alignment of the pipes. Subsequently, the filling and compaction control is carried out. The contract that was executed consists of the installation of pipes of different diameters manufactured with GRP technology with a length of 923.62 m, through which the rainwater and wastewater from the Marroquin II and Alfonso Bonilla Aragón neighborhoods drain. The project begins at transversal 103 with diagonal 26 p18 and ends by draining in the secondary channel in race 26 O. The project began activities on May 3, 2018 with the materialization of landmarks, georeferencing of GPS points attached to certified plates. by IGAC and the initial topographic survey and activities end on June 30, 2019. During the construction process, the topographic inspection and control of alignments, slope control and verification of pipe deflections is carried out.
